B8

• Carbon dioxide + water --(light)--> glucose + oxygen
• Leaf adaptation : Big surface area

  Thin for short diffusion path

  Chlorophyll

  Guard cells , air spaces for CO2 to come in

  Veins which bring lots of water in xylem
• Photosynthesis is an endothermic reaction
• High light intensity = High rate of photosynthesis
• Temperature increase means photosynthesis increases
• High CO2 concentration means high photosynthesis
• Glucose is soluble in water while starch is insoluble
• magnesium - make chlorophyll

  nitrate- building protein , growth
